SP'ECFIGAT'ION forming part of Letters Patent No. 649,971, dated May 22, 1900. Application filed J' anuary 5, 1900. Serial No. 437. (No model.)

To all whom t may concern:

Be it known that I, MARCUS LAFEYETTE WARMAN, a citizen of the United States, and a resident of Bethel, Clermont county, State of Ohio, have invented a certain new and useful Gate-Operating Mechanism; and I do declare that the following is a description thereof sufficiently clear, full, and exact to enable others skilled in the art to which it appertains ib to make and use the same, attention being called to the accompanying drawings,with the reference-numerals marked thereon, which form also a part of this specication.

This invention relates to improvements in I 5 mechanism for operating swinging gates, particularly such of larger siz'e used to close driveways, and it relates more particularly to gates which are operated some distance in advance, so that while approaching on horseback or in zo a vehicle the gate may be opened and closed from either side without dismounting.

The invention consists of certain mechanism and details of construction for the pur= pose of operating a swinging gate in the manz' 5 ner referred to, all as hereinafter set forth,

and illustrated in the accompanying drawings, in Which-:-

Figure 1 is a perspective view of a gate provided with a mechanism for the purpose of 3o operating it and constructed in the manner as 'contemplated by my invention. Fig. 2 is an edge view of the gate when open, showing' also operating means in corresponding position; and Fig. 3 is a detail view.

In the drawings, 6 indicates a gate of customary construction hinged to a post 7 and abutting when closed against another post S. Beside the driveway, some distance from the gate and about in line with post 7 ,there is alow 4o post 9, to the top of which a link,11 is pivotally connected. The free end of this latter is jointed at 12 to the end of another link 13, connected also pivotally to one of the intermediate members of the gate in the manner and about at the point shown in the drawings.V When the gate is closed, these two links assume a positionwhich brings them in line with each other, which line is disposed at an acute angle to the former, and the posi- 5o tion of the links and the connection of their ends are such that if they are raised at the point of their connection the straight line heretofore formed by them will be broken (see dotted lines in Fig. 1) and their outer or remote ends will approach each other, with the ultimate effectof opening the gate. For so raising these links I provide levers 14, connected thereto by rods 15 and supported on the upper ends of posts 16. These latter are about in line with posts 7 and 9 at equal distance from the location of pivot 12 and with levers 14 projecting in opposite direction, one at each side of the gate, so that this latter may be operated while coming from either direction. -To facilitate this operation, the outer end of each lever may be provided with a pull rod or rope 17; Rods 15 do not connect directly to links l1 and 13, but first to an in'- termediate member 18, which interposed between the connected ends of the links holds them sufficiently apart to cause them to work freely and prevents interference of one with the other. At the same time the weight of this member assists the operation of the gate and the retention of it in either its closed or open position in a manner to be presently eX- plained. In the closed condition of the gate the links being in a straight line form a rigid brace which holds the gate firmly in its closed position, since a stress endwise against these links would be insuliicient to collapse them for the purpose of permitting opening of the gate. The links are held in this locking position by their weight, assisted by the weightof member 18, and to prevent them from sinking below this position one of them, preferably link 13, is continued beyond the point of its connection to link l1 and shaped to form a heel 19, taking over the edge of link 1l, whereby this result is accomplished. For opening the gate one of levers 14 is operated by a short jerky pull, which is continued only until the links are sufficiently raised to bring them at the point where they connect to each other to the highest position they may possibly atta-in', (see highest position in dotted lines in Fig. 1,) at which moment the lever is abruptly released, whereupon the swinging gate complet-es its movement by reason of its momentum, assisted by the weight of the links, which is increased by the additional weight of member 18 and heel 19 of extended link 13, all of which as soon as their combined weight has passed IOO s `4 f V649,97'11? the Center of gravity drop -in the otherdireotion andto a pOSition shown inFig.`2','in ,which een, i or 'omni position'- the generis new heidfby the COmbined weight of the same parts, as above described.` The manipulation for closing the gate is theV same. Another similar pull is exerted upon vone of the levers siiicient only to raise'thef operating parts from the position shown in Fig.- 2 to lthe highest one shownin dotted lines in Fig. 1, whereupon the momentum of` the gate, together with the Weight of the parte, carries the gate toits olosing position, in which it is heldgby the position and Weightofthe parts.
